LAUNDRY-STOVE.

Application filed May 23,

Z '0 all whom it may concern:

Be it known that 1, CHARLES P. Mnhvrn, a resident of Youngstown, in the county of Mahoning and State of Ohio, have invented a new and useful Improvem nt in Laundry- Stoves, of which the follow is a specification.

This invention relates to stoves and particularly to stoves for use in laundries ETK like places for supporting a wash boiler 01 like vessel while heating the contents. The object of the invention is to provide a stove' of simple construction, which can be readily fabricatec with a minimum amount of labor and at small cost, and which is nevertheless strong and substantially unbreakable.

The invention comprises a stove constructed as hereinafter described and claimed.

In the accompanying drawings Figure l is a plan view of the stove; Fig. 2 is a central vertical longitudinal section thereof; Fig. 3 is a transverse section of Fig. 1; and Fig. 4: is a plan view of the blank forming the main frame member before it is bent to shape.

The stove comprises a main frame member 1, a plurality of rests 2 for the boiler or other article secured to the frame member, legs 11 for supporting the frame member, and a gas burner 14 supported in the frame member; substantially all of said parts being formed from wrought metal, preferably rolled strap or similar metal and commercial tubes.

The main frame member 1 is formed from rolled strap or band metal which, after being perforated and notched as hereinafter described, is bent to oval or other form, depending upon the shape of the vessel to be supported, and has its ends united. The rests 2 for the boiler or other vessel are likewise formed from rolled strap or band metal suitably notched and interlocked edgewise with the main frame member. In the particular embodiment illustrated, which is the preferable form for supporting wash boilers and the like, the main frame member is bent to oval form. \Vhile still in the flat it is punched with the holes and notches shown in Fig. 4, to wit, with a series of kerfs or notches 3 in its upper edge, the number thereof depending upon the number of rests to be secured thereto; a pair of holes 4 at each end for receiving the means, such as rivets 5 or the like, for securing together the ends Specification of Letters Patent.

of said band; four sets of holes 6 intermediate its ends for the attachment of the legs; and a pair of large holes 7 located fairly close to the lower edge of said bands for receiving the burner tube. This blank, after being notched and perforated as illustrated is bent to the desired shape, by any suitable bending means, and the ends thereof are united by the rivets 5, bolts or the like, extending through the holes 4..

The rests 2 for the boilers or other vessel are nothing more than short sections of strap or band metal, preferably somewhat narrower than the main frame member 1, and are out from continuous lengths of such metal by a simple shearing operation, having their ends beveled as shown in Fig. 3. They are provided on their lower edges with a pair of kerfs or notches 9 for interlocking with the notches 3 of the main frame member. Inasmuch as these rests can be sheared from continuous lengths in reverse position, little or no metal is wasted because of'the beveling of the ends. The kerfs 3 of the main frame member are so located that when said memher is bent to final form said kerfs are arranged in oppositely disposed pairs. and the kerfs 9 in the rests 2 are of such distances apart that they will interlock with the kerfs 3. The kerfs 8 and 9 are of'such width as to form a tight fit with the opposing member so that these parts are assembled by simply driving the rests into the notches 3 of the main frame member. said notches 3 holding the rests against displacement endwise of the main frame member, while the kerfs 9 prevent displacement of said rests sidewise of the frame. The two end rests, indicated at 2 are identical with the others but are bent to curved or angle form, as shown in Fig. 1, so that their kerfs will be brought into proper position to interlock with the two kerfs located in the curved end portions of the main frame, with the ends of said rests projecting outwardly at an angle to support the ends of the boiler. This bending of the end rest can be effected on any suitable bending machine or even by simple bending devices.

The legs 11 are formed of short pieces of rolled bars of any section, the drawing showing the same formed of small channel bars. These are cut from long lengths of bars, and need no fabrication other than punching a, pair of holes near one end to receive the the tube in the frame in the opposite direcfastening bolts, rivets or the like 12 extending through the holes 6 of the main frame. Preferably these leg sections will be given a slight bend near their upper ends in order to cause the bottoms thereof to spread apart and form a more stable sup ort. p The burner is formed of a section of commercial tubing 14 extending through the holes 7 in the main frame member, and affordsa center support for rests 2, and is provided in its top side with a series of small perforations 15 for the escape of the gas. This tube is of a size to have aneasy fit in the holes 7, is threaded at one end to receive the closing cap 16 which prevents displacement of said tube lengthwise of the frame in one direction, and at its opposite end is plain and has secured thereto, such as by means of set screw 17, the gas mixer and valve 18, which prevents displacement of tion. Themember 18 is preferably a casting,.having threaded'into its outer end the gas connection 1.9 through which is threaded the stem of the control valve 20 provided on its outer end with a regulating hand forms an air and gas mixer. The amount wheel of the usual kind.

The member 18 18 provided on opposite sides wlth openings 21 for the adm1ss10n of air, and in effect of air admitted at this point can be regulated by loosening the set screw 17 and sliding the member 18 lengthwise of the tube so that the end of the'tube will shut off the openings 21 more or less.

The stove described is of very simple construction, can be fabricated by the use of ordinary machinery and without skilled labor. The operations are few in number and very simple so that the labor cost is low. The entire stove, with the exception of the gas connection and mixer is formed of Wrought metal which may be commercial stock and therefore procurable at low cost and which also is very strong so that the stove although of minimum weight is practi cally unbreakable, and will stand-shocks and jars much more effectively than castings. There are no special part-s required for the stove, and said stove can readily be knocked down, by removing the legs, so that it will pack in compact form for shipment.

. I claim: 7

A stove comprising aframe member of band metal bent to substantially oval form,

with its ends united andprovided with a pair of oppositely disposedholes, flat bar metal rest members edgewise interlocked with the frame member by interengaging kerfs, the

end rests being bent'in substantial V-shape to interfit with the kerfsin the end por tions of the frame member, legs secured to said frame member, and a perforated gas burner pipe extending through the oppositely disposed holes in the frame member.

In testimony whereof, Ihave hereunto set my hand. i
